Miggo AIRoot Cause Analysis

The vulnerability stemmed from two key issues: 1) Insecure URL construction in PDF resource handling that failed to properly escape user-controlled PDF URLs, allowing parameter injection. 2) Dangerous unescaping rules when parsing the PDF src parameter that permitted spoofable characters. The GitHub patch shows the addition of net::EscapeUrlEncodedData for proper encoding and removal of unsafe unescape rules, directly addressing these vulnerable code paths. The added test case verifying URL escaping confirms these were the attack vectors.
